Application filed September 12, i901. Serial No. 75,ll9. (No model.)

To @ZZ whom it may concern.-

Beit known that I, FORE BAIN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Rail Joints; and I hereby declare that the vfollowing is a full, clear, and exact description thereof, reference being had to the accompanyingk drawings, which form part of this specification.

My invention relates to improvements in railway-rail joints. y y

The object of my invention is to provide a rail-joint by means of which the abutting ends ofthe adjacent rails in a railway-track will be iirmly and intimately heldl together, so as to provide a result that for all intents and purposes is equal, in effect to that of a continuous unbroken rail. v

Bymeans of my joint the heads of the adjacent rails are. supported in a vertical posi-- tion and the rails are bodily supported against the lateral outwardly-extended strain of the passing train. The mobility of the ends of the rails with reference to each other is avoided when supported by my joint, while sufficient elasticity and strength are aorded by providing an unbroken metal support under. the

base of the ends of the rails through the entire length of the joint, and a vertical relative displacement of the rails is thereby prevented. The arched outwardly-curved vertical portion contained between the under side of the head and the ange of the rail is strengthened by Webs or braces in a plane where the rails meet, which adds great strength to withstand the transverse, vertical, and lateral stress and shock to which the joint is in practice subjected. The economical distribution of metal in the general form and construction of my joint provides one of the highest realizations of strength, rigidity, and elasticity for the purpose for which it is designed.

The drawings show the embodiment of my invention, in Which- Figure l is a side `elevation of my joint, showing the tie-plate midway between the ends thereof. Fig'. 2 is a plan view of the same, showing the manner in which it rests upon the tie. Fig. 3 is a transverse section through lines 3 3 of Fig. l. Fig. 4 is a side elevation of my joint, showing one section only used in connection with an ordinary fishplate or angle-bar, the one section of my imy which are shown in Figs. 1, 2,'and 3 andare i designed to be placedon opposite sides of the rails and bolted Ytogether by means ofbolts passing through the vertical web of the rail and also byv means of other bolts passing un-l der the base of the rail and located on either side of the cross-tie. j In the joint shown in Fig. 3 only ono section used in connection with the ordinary anglebar or fish-plate. In this event I extendthe rail base-plate entirely under the rail and have it project slightly beyond the base of the Aor member of my joint is necessary. Itis rail, so as to provide a means for spikingr the base-plate and the angle-bar to the cross-tie. a and a' and h and h are lateral extensions of the rail-base support of each section 'of the joint. They are located in the center of the section and supportthe joint upon'the tie.

, c and c' are the vertical arched outwardlycurved sections, which have bearings and form supports between the top surface of the base and the under surface of the head of the rail. i I

l The sections are perforated with holes for the admission of bolts for holding the said immediately above which the abutting 'ends of the adjacent rails meet. Bolts a9 are adapted to pass through the upper part ofthe sections and through the vertical Webs ofthe rails. I join the section c with theplateb, at a point in a plane through the meeting-point of the rails by means of a brace 0.6 andb?.

They extend from a point near the topof the vertical outwardly-curved or arched portion o to the bottom of the base portions tand b.

They increase the cross-section through the plane where the two rails meet and add greatly to the rigidity and strength of the joint at the point subjected to the greatest strain.

as and D8 are perforated bosses which are provided on the lower part of the rail beyond the tie-plate or on either side thereof, through` which the bolts a and am are designed to pass and by means of which the lower parts of the joint are forced into contact with the sides of the rail.

Thejoint consists, essentially, of a baseplate placed in the center of the joint, which is designed to rest upon the tie, a vertical outwardly-curved or arched portion,and a foldedover portion, which joins the base-plate with the said curved portion, these parts being reinforced or strengthened by thin ribs or braces properly disposed.

The ribs a2 and a3 and b2 and b3 extend from points near the top of the vert-ical curved portion c to the top of the laterally-extended extremities a and b of the base-plate, which pass also under the rails A and A'. These ribs form rigid braces or webs for su pporting the curved arched portion in a vertical position and for holding the base-plate in the proper relation thereto.

y The laterally-extending base-plates afford a large surface in contact with the top of the tie upon which the rail rests, so that the weight which comes upon the rails by the passing of the train will not cause the structure to be embedded in the ties on account of the larger surface over which the pressure is distributed.

There is sufficient space between the inner surface of the vertical outwardly-curved or arched section and the vertical web of the rails for containing the electric bonds that are generally usetl'for electrically joining the abutting ends ot' the rails, so that the rails may be bonded together by the usual method and the bonds covered by the joint, and thus protect it from' accident or intended injury. When the joint-sections are drawn together by means of the various bolts, the vertical curved portion having correspondingly-angled engaging surfaces, is wedged in tightly between the under surface of the rail and the top surface of the flange and does not come in contact with the vertical web of the rails.

/Vhen a single section of my joint is used, as shown in Figs. 4, 5, and b', an ordinary lishplate or angle-bar, as shown in dotted lines in Fig. 6, may be used in connection therewith. In that event the base-plate Ct is extended under the rail and beyond the limit of the said fish-plate, so that a spike may be inserted through the openings a and dii.

By the construction which I have shown and described the head of the rail is directly supported by the arched outwardly-curved section. A portion of the Verticalstress comes directly through the rail-head and angle-bar and is distributed over the larger surface, which bears directly upon the tie. By means of the arrangement of the parts-the curved portion, rail-bases, braces, and tie-plates-the rail is sustained in a vertical position against lateral thrusts and strains.

All of the parts of my rail-joint are made of a thin but uniform cross-section, so that when the joint is made of malleable iron the annealing process will affect the entire mass of material of which the joint is composed and penetrate sufficientlyto render all of the metal malleable, tough, and strong.

All of the Webs and braces of my joint are distributed so as to afford the greatest strength and elasticity, and the webs which connect the folded portion with the outwardlycurved portion provide a means for adding great strength to the said sections without proportionatelyincreasing the Weight thereof.

Having described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

l. In a rail-joint for securing the ends of rails together', the combination of two like Vertical sections curved outwardly from the Web of the rail, each adapted to Vfit the rail along itsentire length between the under surface of the head and the flange thereof, a rail base-plate under the base-surface of the rail, extending longitudinally the entire length ot' the joint, and extending laterally from the middle thereof, forming the tie-plates, an intermediate folded portion between said baseplate and said vertical curved portion, vertical webs connecting said vertical portion, folded portion and tie-plates, and other vertical webs connecting said vertical, outwardly-curved portion and said folded portion at points between said tie-plate and the ends of said section, substantially as set forth.

2. In a rail-joint for securing the ends of rails together, the combination with an ordinary angle-bar, or fish-plate, of a vertical, outwardly-curved section adapted to fit the rail along its entire length between the under surface of the head and the flange there of, a continuous-rail base-plate under and beyond the base-surface of the rail, extending uninterruptedly and longitudinally the entire length of the joint-section, and extending laterally to form a central tie-plate, an intermediate, folded portion between said base-plate and said vertical, curved portion, vertical Webs connecting said vertical portion, folded portion and central tie-plate, other vertical Webs connecting said Vertical portion and bolts for securing the said anglebar and said section to the rails, and said folded portion, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
